What would happen if a major predator was removed from the food web?

Prey population explosion

Explanation:

If a major predator is removed from the ecosystem, it will disturb the predator-prey relationship in the ecosystem that will result in the direct increase in the prey population. This phenomenon is called population explosion where there is no check and balance on the prey population.

For example, if there is a major predator in the forest ecosystem it will feed on herbivores and keep their population at a certain level. This is called predator-prey balance where predators kill prey which in-turn cause food scarcity for predators and leads to a decrease in predator population too. So if any major predator is removed from ecosystem it will disturb this intricate balance.
